potentiometer typo?

Hi, I've made some modifications to a steering wheel and pedal set by replacing the 10K pots with 100K pots. This was done according to the Operator Interface reference guide. On page 5, they show a wiring diagram for a typical 100K potentiometer. The way I've used pots in the past are as variable voltage dividers. By taking a look at the wiring diagram, the third pin is labeled to have no connection. If this is true, then the pot would act as a variable resistor instead of as a voltage divider. I was wondering if this is a typo, or if I should disconnect the ground lines of the pots in the steering wheel and pedal set.

Thanks,
Windell
